Be it known that I, HARRY SANFORD GAR- DINER, a citizen of the UnitedStates, and a resident of Amsterdam, in the county ot' Mont- .I S gomeryand State of New York, have invented a new and 'Improved Gage, of whichthe follc'iwing is a full, clear, and exact description.Theinventionrelates to measuring instruments; and itsobject is toprovide a new and I improvedgage, more especially designed for 4conveniently and quickly determining the 1 `sizes of twist-drills andother objects and to gage wires and the like. 1;Q Theinventionconsists'of novel features and I5 partsand l'combinations of the same,as will be more fully described hereinafter and then pointed out in theclaims.

` Apractical embodiment of the invention is frepresented in theaccompanying drawings, f2o forming a part of this specification, inwhich Asimilar characters of reference indicate corresponding parts 1nall the views.

Figure l is a perspective view of thel improvement asapplied for gaginga wire. Fig. 2. is a'V rear face view of the improvement arranged formeasuring a rectangular bar both fj in width and thickness. Fig. 3 is alongitu- ,dinal sectional elevation of the improvement j on the line 3 3of Fig. 2, and Fig. 4 is a trans- 0 Vverse section of the same on theline 4 4 of Fig. 3.

,forbody A, having at one side a longitudinal fe'Xtension-arm iA',terminating at its outer end in a transverse gage-arm A2, having itsinner edge at right angles to the extension-arm A'.

On one face of the frame A is formed a longitudinal guideway A3, inwhich is mounted to move longitudinally a slide B, adapted to 40 befastened in any desired position on the `.frame A by a suitableclamping-screw C, which when unscrewed also serves to move the slide Blongitudinally into the desired place. The slide B is provided with anintegral head B', having its outer edge parallel and adjacent to theinner edge of the gagearm A2, and on one face of the said slid'e isarranged a longitudinal graduation D, indicating linear measurement,preferably in HARRY SANFORD GARDINER, OF AMS'llCltDAM,

Fig. 2it will he seen that the bar can be read on width of the bar thicknessof this the graduation Dand the on the graduation E. On the other faceof the slide B is arranged a graduation F, (see Fig. 1,) representingthe size of wires and the like, the graduation consisting of transversellines arranged in three adjacent longitudinal columns, and the linesare numbered according to Wire-gage numbers and read ofi' along thebeveled edge of a cross-bar A, forming part of the frame A and securedto the sides thereof opposite the beveled edge A4. These columns arepreferably three in number, and the central column is provided withclose graduations, while the graduations of the columns at the sidesthereof are spaced twice as far apart and alternate with each other inextending from the middle of the spaces between the graduations of thecentral column.

In gaging a wire the latter is placed between the gage-arm A2 and thehead B', as plainly shown in Fig. l, the wire is read off on thegraduation F-that is, on the line coinciding with the beveled l edge ofthe cross-bar A5.

A gage, comprising a flat frame having a guideway onone side, an extension-arm extending forwardly from the end of the gage,and terminating in a transverse gage-arm extending inwardly from the end.of said eXtension at right angles thereto, the inner edge of saidgage-arm being parallel with the forward end of the frame, a slidereceived into said guideway, and movable on the frame toward and fromsaid gage-arm, an integral head on said slide projecting laterally fromthe side edges thereof to form a stop for the slide when movedrearwardly, a cross-bar on the upper face of the frame extending acrossthe guideway at the forward end thereof, the front edge of saidcross-bar and the corresponding front edge of the frame being beveled,the slide having on its front side a longitudinal graduation readingforwardly toward the head of the slide and terminating at said head, anda transverse graduation on the head reading outwardly from the rear sideof the slide to the front side thereof, wire-gage graduations on theopposite side of *the slide comprising transverse lines in separatecolumns, one of said columns having comparatively close graduations andthe columns at the side thereof having graduations spaced twice as far'765,471 EST AVN @M3115 QG@ apart and alternating with each other in eX-tending from the middle of the spaces between said close graduations,and aclampingscrew carried on said slide and adapted to engage the frameto lock the slide in any desired position thereon.

A gage comprising a frame having a guideway, an extension-arm extendingfor-` wardly from the end of the gage, and an 1n' tegralinwardly-extending transverse gagearm at the forward end of saidextension-arm, said gage-arm being disposed at a right angle to saidextension-arm and parallel with the forward end of the frame, a slidefitting in said guideway and movable toward and from said gage-arm, andan integral head on said slide to form a stop therefor, said slide beingprovided on one face with wire-gage graduations comprising transverselines in columns, and on the other face with longitudinal and transversegraduations located respectively at the front side and forward end ofsaid slide.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
